Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A User Equipment (UE) comprising: a controller; and transmitting and receiving circuitry configured to: transmit, to a core network, a request message for requesting authorization of establishment of a direct communication path between the UE and a proximity UE; and receive, in response to the request message, from the core network, first information indicating that the establishment of the direct communication path has been authorized, wherein the proximity UE is positioned in proximity to the UE, the first information includes at least an IP address and frequency information, the IP address and the frequency information are used by the UE to perform direct communication with the proximity UE, after the first information is received, the controller is configured to initiate a discovery procedure for the proximity UE, after the discovery procedure is completed, the transmitting and receiving circuitry is configured to perform direct communication with the proximity UE using the established direct communication path, and a destination of the request message is the core network.
This invention relates to wireless communication systems, specifically enabling direct communication between User Equipment (UE) devices in proximity to each other. The problem addressed is the need for efficient, authorized direct communication paths between UEs without relying on traditional network infrastructure, reducing latency and conserving network resources. The UE includes a controller and transmitting/receiving circuitry. The circuitry sends a request message to a core network, seeking authorization to establish a direct communication path with a nearby UE (proximity UE). The core network responds with authorization information, including an IP address and frequency details, which the UE uses to communicate directly with the proximity UE. After receiving this information, the UE initiates a discovery procedure to locate the proximity UE. Once the discovery is complete, the UE establishes and uses the direct communication path for data exchange, bypassing the core network for subsequent transmissions. The system ensures secure and authorized direct communication while leveraging network assistance for initial setup. This approach optimizes resource usage and improves communication efficiency between nearby devices.
2. A core network device comprising: transmitting and receiving circuitry configured to: receive, from a User Equipment (UE), a request message for requesting authorization of establishment of a direct communication path between the UE and a proximity UE; and transmit, to the UE, in response to the request message, first information indicating that the establishment of the direct communication path has been authorized, wherein the proximity UE is positioned in proximity to the UE, the first information includes at least an IP address and frequency information, the IP address and the frequency information are used by the UE to perform direct communication with the proximity UE, the first information is used by the UE to initiate a discovery procedure for the proximity UE, and a destination of the request message is the core network device.
This invention relates to wireless communication systems, specifically enabling direct communication between User Equipment (UE) devices in proximity to each other. The problem addressed is the need for efficient, authorized direct communication paths between UEs without relying on traditional network infrastructure, reducing latency and conserving network resources. The core network device includes transmitting and receiving circuitry that receives a request message from a UE seeking authorization to establish a direct communication path with another UE in close proximity. The core network device responds by transmitting authorization information to the requesting UE. This information includes an IP address and frequency details, which the UE uses to initiate direct communication with the proximity UE. The authorization also includes instructions for the UE to perform a discovery procedure to locate the proximity UE. The request message is specifically directed to the core network device, ensuring centralized control over direct communication authorization. This system enables seamless, low-latency direct communication while maintaining network oversight.
3. A communication method performed by a User Equipment (UE), the communication method comprising: transmitting, to a core network, a request message for requesting authorization of establishment of a direct communication path between the UE and a proximity UE; and receiving, in response to the request message, from the core network, first information indicating that the establishment of the direct communication path has been authorized, wherein the proximity UE is positioned in proximity to the UE, the first information includes at least an IP address and frequency information, the IP address and the frequency information are used by the UE to perform direct communication with the proximity UE, after the first information is received, the UE initiates a discovery procedure for the proximity UE, after the discovery procedure is completed, the UE performs direct communication with the proximity UE using the established direct communication path, and a destination of the request message is the core network.
This invention relates to a communication method for establishing a direct communication path between a User Equipment (UE) and a nearby proximity UE, bypassing traditional network infrastructure. The method addresses the challenge of efficiently enabling direct communication between UEs in close proximity, reducing latency and conserving network resources. The UE transmits a request message to a core network, seeking authorization to establish a direct communication path with a proximity UE located nearby. The request message is specifically directed to the core network. In response, the core network provides authorization in the form of first information, which includes an IP address and frequency information. These details are used by the UE to initiate and maintain direct communication with the proximity UE. Upon receiving the authorization, the UE performs a discovery procedure to locate the proximity UE. Once the discovery is complete, the UE establishes and uses the direct communication path for data exchange. The direct communication leverages the provided IP address and frequency information, ensuring efficient and low-latency communication between the UEs. This method streamlines proximity-based communication, enhancing performance and resource utilization in wireless networks.
4. A communication method performed by a core network device, the communication method comprising: receiving, from a User Equipment (UE), a request message for requesting authorization of establishment of a direct communication path between the UE and a proximity UE; and transmitting, to the UE, in response to the request message, first information indicating that the establishment of the direct communication path has been authorized, wherein the proximity UE is positioned in proximity to the UE, the first information includes at least an IP address and frequency information, the IP address and the frequency information are used by the UE to perform direct communication with the proximity UE, the first information is used by the UE to initiate a discovery procedure for the proximity UE, and a destination of the request message is the core network device.
This invention relates to a communication method for enabling direct communication between user devices in proximity, addressing the need for efficient and authorized direct communication paths in wireless networks. The method is performed by a core network device, which receives a request from a User Equipment (UE) seeking authorization to establish a direct communication path with another UE in close proximity. The core network device processes this request and responds with authorization information, including an IP address and frequency details, which the UE uses to initiate direct communication with the nearby UE. The provided information also supports a discovery procedure to locate the proximity UE. The core network device acts as the destination for the initial request, ensuring centralized control and authorization of direct communication links. This approach enhances communication efficiency by reducing reliance on traditional network infrastructure while maintaining security through core network oversight. The method supports seamless direct communication setup between UEs in proximity, leveraging network-provided parameters for reliable and authorized connections.
